    HHO tuning for hydrogen dry cells

    I am looking for anyone that is experimenting using HP tuners to dial in the use of hydrogen fuel cell generators know as HHO dry cells. There are chips available and maf/map foolers but I know Hp tuners can do this. The afr stoich will have to be lowered to compensate for the added oxygen in the exhaust but what if the hho is off. Will the vehicle then be run lean? Would a separate o2 widewand still be accurate to tune with? With high gas prices this seems like a good time to dive into this.
